END STRUCTURE FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Nov. 28,1916.

To all'whom it may concern:

Be it known that I, PERCIVAL H. TRUMAN, a citizen of the United States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in End Structures forRailway-Cars, of which the following is a specification. My inventionrelates to sheet steel end structures for railway cars particularlysuitable for box freight cars. The regulations of the InterstateCommerce Commission require certain clearance between the portions ofthe ends of a box car. where the end ladders are placed, the objectbeing to insure the safety of trainmen using the ladders. This reuirement does not apply to the center portion of the end of the carwhich may be made to bulge or project beyond the portions at the sidesof the car.

The primary object of my invention is to provide a car end structurewhich takes advantage of the fact that the center portion or the end myproject out beyond the side portions and utilizes this space. at thecenter of the car for giving added strength and rigidity to the endstructure without diminishing the loading capacity of the car.

The invention has for further objects such other new and improvedconstructions, arrangements and devices in sheet metal car ends as willbe hereinafter described and claimed.

The invention is illustrated, in certain preferred embodiments, intheaccompanym drawings, whereinigure 1 shows, in elevation, a sheet metalcarend, of one type, constructed in accordance w1th my invention. Fig. 21s a vertical sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional plan on line 33 of Fig.

1. Fig. 4 is a view, in perspective, of one of the intermediate elementsor panels making up the end structure. Fig. 5 is a fragmentary sectionalview illustrating a modification. Fig. 6 is an elevation of another formof the invention. Figs. 7 and 8, sectional views taken on lines 7--7 and88 respectively, of Fig. 7; Fig. 9, a view in ective of one of thepanels making up lid gnd shown in the preceding three figurea; Fi 10, asectional view similar to Fig. 8 owing a modification; Fig. 11, a view,"in perspective, of one of the panels employed in the modifiedconstruction 29; the

shown in Fig. 1O; Fig. 12, an elevation of another embodiment of theinvention; Figs. 13 and 14, sectional views taken on lines 13- -13 and1414, respectively; of Fig. 12.

Llke characters of reference designate like parts in the several figuresof the drawings.

The end structure shown in Figs. 1 to 4 inclusive is made up preferablyof an upper panel 25 securedto the end plate 26 of the car, alower-panel 27 secured to. the end sill 28 and a plurality ofintermediate panels lower edges of the panels 25 and 29 being offset asshown at 30- and overlapping the panels respectively below them. Each ofthe several panels is formed with angularly disposed lateral flanges 31secured in any sultable manner to the corner posts 32 of the car. Eachpanel is formed with an inturned corrugation 33 which preferably deepenstoward the center of the panel-so that it provides a truss-like memberextendmg across the concavity of the panel. Preferably the corrugationsare pressed in to substantially the plane of the outer faces of thecorner posts. That is, the depth of the corrugations at the verticalsection is substantially equal to thebulge of the panel at that point.This gives a maximum reinforcement without the waste of any space withinthe end framing of the car. The structure may be further reinforced byforming the panels 29, and also if desired, the lower panel 27, withinturned flanges 34 on their upper edges which serve the same functionas the corrugations 33 forming truss or tie members resisting thedeflection of the panels under stress of cargo thrusts. The number ofpanels constituting the end might be increased or decreased as might befound expedient.

In Fig. 5 the panels 27*, 30 are formed with flanges 34 but are notcorrugated.

In the construction shown in Figs. 6 to 9 inclusive, the end consists offour triangular panels 44, 45, 46, 47 preferably formed withcorrugations 48 and at their meeting edges with outstanding flanges 49secured together by rivets 50,-the flanges being widest-at the centeroint of the end and tapering down to noth 'ng at the corners. The panels44, 46 are formed with angular flanges 51 for attachment to the cornerposts 32. The upper panel 47 has a flat margin 52 in the plane the endplate 26. The corresponding marginal portion 54 of panel 45 ispreferably bent inwardly and secured to the upper surface of the endsill 28 by bolts 55.

Figs. 10 and 11 sliow a modificatmn of the construction just described.The panels designated 44, 45 46 and 4-7 are formed so that they areinclined toward the center point of the end, that is, toward the apex ofthe triangle in each case, and are providedwith inturned flanges 49 attheir meeting edges. In other respects the construction may be exactlythe same as that shown in Figs. 6 to 9 inclusive.

The construction shown in Figs. 12 to 14 inclusive consists preferablyof an upper sheet 65 and a lower sheet 66 formed with convex portions 6768 and united by a line .of rivets 69. The center portion of the endwhich is of spherical curvature, is reinforced by providing the lowersheet 66 with an inturned flange 70.

I claim:

1, An end structure for railway cars comprising a plurality ofrectangular metal end sheets secured together, formed at their meetingedges with inturned angular flanges,

and disposed so that the structure projectsout farther at its verticalcenter line than at the sides.

2. An end structure for rallway cars comprising a plurality of metal endsheets secured together, disposed so that they bulge out at the centerand formed with interior flanges constituting trusses across the bulgedportion of the end.

3. An end structure for railway cars comprising a plurality of metal endsheets secured together, disposed so that said struc-' ture bulges outat the center and formed at their meeting edges with inturned flanges.

4. A11 end structure for railway cars comprising a plurality ofcorrugated metal end sheets secured together, formed at their meetingedges with'inturned angular flanges, and disposed so that the structureprojects out farther at its vertical center line than at the sides.

5. An end structure for railway cars com-' prising a plurality ofcorrugated metal end sheets secured together, disposed so that theybulge out at the center and formed with interior flanges constitutingtrusses across the bulged portion of the end.

6. An end structure for railway cars com- Ooples of tliis patent may beobtained for mg across the car from side to side with the edges ofadjacent panels overlapping and formed with inturned flanges.

9. An end structure for railway cars com prising a plurality of bowedpanels extending across the car from side to side with the edges ofadjacent panels overlapping and formed with inturned flanges and withinwardly pressed horizontal corrugations.

10. The combination with the end' framing of a railway car, of a sheetmetal end structure which is bulged outwardly from' said end framing andformed with reinforcing corrugations which extend from one corner postto the other and throughout their length are pressed inwardly tosubstantially the plane of the outer surface of thee 11d framing of thecar.

11. The combination with the end framing of a railway car, of a sheetmetal end structure which .is bulged outwardly said end framing withasubstantially imicorrugations which extend from one corner formcurvature from top to bottom of the end and formed with horizontalreinforcing post tothe other and throughout their length i g i arepressed inwardly to substantially the plane of the outer surface of theend framing of the car.

12. A sheet metal end structure for railway cars which is convex andformed with one or more inturned corrugatlons, the depth of which at anysection taken across the 1 same is substantially the'same as the amountof convexity of the end structure at that Witnesses: I
